The Magnum 500w power supply propels MGE into a market they haven't been before, highest end PSUs. Their newest offering presents many of the best attributes on the market and then adds a few others to top it off. There have been silent power supplies before from companies such as PC Power and Cooling or Antec, but none have taken it to the level that MGE has, a full size copper heatpipe. This alone will extend the life of the PSU, heat is one of the primary killers of computer parts. Combine that with a decent fan to provide some ventilation and airflow and you have a killer combination.
